I have a technical question. Do we have to use p-value
for selecting independent variables fro multivariate
analysis?
Example:
I have 3 independent variables a, b, c which I have to
regress on dependent variable y.
In independent variable, the p-value for variable a is
0.09, varable b is 0.23 and variable c 0.77. If I have
to do multivariabte analysis, is it necessary to
reject variable c because the p-value is 0.77??
In multivariate analysis, does order of entering
variables make a difference??
Please advice, Thanks in advance.
